Bluebird Project

HARP has sought to make sustainable choices wherever possible, resulting in a gas-free approach to the new build with six air source heat pumps that serve the heating and hot water requirements. 

Bluebird has incorporated a number of wider considerations which contribute to the overall sustainability of the development. The main structure of the building is a twin-stud timber frame incorporating Warmcel recycled newspaper insulation. Conscious materials have been used including natural cork boards which allow residents to make the space their own, and Cradle to Cradle certified materials including the carpet which is Bronze Certified.

The project has incorporated flow restrictors or low usage fixtures and appliances to reduce water consumption. Rainwater collection is utilised by residents to water the gardens. Passivhaus-certified Mechanical Ventilation with Heat Recovery (MVHR) units were also installed to provide high indoor air quality whilst minimising heat loss.

To achieve Passivhaus certification the project adopted a rigorous approach to the overall form, orientation, quantities of glazing, solar shading and services throughout the design development. 

Following a review utilising PHPP software with the Passivhaus consultants, WARM, the originally proposed quantities of glazing were reduced while the overall proportions of the openings were maintained by using PPC aluminium panels to maintain the relief in the clay tile and further introducing colour to the façade. 

Chamfered aluminium canopies are also incorporated to the rear to protect the building from both current and future overheating whilst providing a sheltered area for socialising.
